3/8" Clear Extruded Acrylic Sheet - 48" x 96"

Why Choose 3/8" Clear Acrylic at Full Sheet Size?

The 3/8" thickness represents heavy-duty acrylic for specialized applications that demand more than standard thicknesses can provide. This substantial sheet delivers exceptional structural mass for extra-long unsupported spans up to 72 inches, handles water pressure for large aquarium viewing panels, and provides the extreme rigidity required for architectural glazing in demanding environments. At approximately 71 pounds per full sheet, this is serious material for serious applications where maximum acrylic thickness provides necessary performance that thinner options cannot match.

With 92% light transmission—superior to polycarbonate—this thickness maintains acrylic's renowned optical clarity advantage while delivering structural performance that approaches glass in rigidity. The full 48" x 96" size enables large-scale installations for architectural windows, commercial aquariums, and specialty glazing applications where crystal-clear transparency and substantial material thickness both matter. When specifications require acrylic material beyond standard 1/4" thickness, when engineering calculations demand extra rigidity, or when you need the confidence of maximum available acrylic, 3/8" delivers performance that standard thicknesses cannot provide.

This Thickness Excels When You Need:

• Maximum acrylic structural rigidity - Exceptional deflection resistance for extra-long unsupported spans up to 72 inches or demanding applications requiring substantial material beyond standard 1/4" thickness
• Water pressure resistance - Substantial thickness required for large aquarium viewing panels, water features, and marine applications where material must withstand significant hydrostatic pressure
• Heavy-duty architectural glazing - Maximum material presence for architectural installations, large-format windows, and commercial applications requiring premium thickness with crystal-clear transparency
• Specialty engineering requirements - Meets demanding specifications for applications where engineering analysis indicates standard thicknesses provide insufficient structural capacity or safety factors
• Extended service life in demanding conditions - Maximum material volume provides superior long-term durability in high-visibility installations requiring both structural integrity and maintained appearance

Extruded acrylic offers excellent dimensional stability and superior optical properties, making it the professional choice for specialty applications requiring maximum material thickness with exceptional clarity.

When to Choose 3/8" Acrylic Over Other Thicknesses

Select 3/8" acrylic when engineering specifications explicitly require material beyond 1/4" thickness, when you're building large aquarium viewing panels requiring water pressure resistance, or when architectural installations demand maximum acrylic rigidity for extra-long spans. This thickness is also specified for large-format windows requiring substantial material presence, specialty display applications needing extreme clarity with maximum structural capacity, and any installation where standard 1/4" acrylic provides insufficient performance margins.

For most architectural glazing, replacement windows, and display applications, 1/4" thickness provides adequate performance at substantially lower cost and weight. However, when specifications mandate maximum acrylic material, when aquarium applications require pressure resistance, or when extra-long spans demand maximum rigidity while maintaining superior optical clarity, 3/8" delivers the performance you need. This is specialty material for applications where standard thickness is genuinely insufficient and crystal-clear transparency remains a priority.
